Make your standards inconvenient to mediocrity.

When your standard is high and steady, average work becomes uncomfortable to hand you, to do near you, and to accept from yourself. That is not about being harsh with people. It is about the way a clear line changes what feels acceptable in a room, including in your own head. Mediocrity survives best in places where nothing is defined precisely enough to fall short of.

Name the standard you actually hold for one part of your work, in a sentence specific enough to fail. Then hold it on the day you are tired. That is the day the standard is either real or decorative.
